Hi Raphael,
Its not possible to update references without opening the espace . When you publish it through service studio it compiles the esapce completely and generate the code with the latest reference uses.

In addition, you should be careful because in ServiceCenter the solution publishes the dependencies of the solution's espaces. If your espace is consuming a SilkUI module for example, this module will also be republished, and other espaces that references it can be out of date.
